Integrating devices is impossible without some sort of standardization. Think about it, what do you do when you get a computer built by one manufacturer and some piece of hardware developed by another manufacturer? You need the driver software for the said device. This is exactly how devices in the IoT realm will work. For integration, these devices are going to need some sort of connecting or interfacing mechanism. Otherwise, data being sent across devices may just get interpreted in the wrong manner, if it ever gets received to begin with. That said, integration and integrity of data both depend heavily on standardization of these techniques and practices.

How do you ensure the correct data got sent? And how do you ensure, no one was eves dropping over a wireless connection with its infinite access points? You require stringent security measures to make sure people with malicious intent as well as ill-designed devices don’t end up breaking the integrity of the system and causing disruption. Otherwise, over a network that connects thousands and maybe even millions of devices across borders, ensuring the correct and sole reception of data being sent can become your worst nightmare.
